BEVELING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 678,037, dated July' 9,1901. Appiioation tied April 12, 1900. SerlNo. 12.620i (Nomade.)

To cLZZ whom t may concern:

Be it known that I, VERNON ROYLE, a citizen of the United States, and aresident of Paterson, in the county of Passaic and State of New Jersey,have invented a new and use ful Beveling-Machine, of which the followingis a specification.

My invention relates to beveling-machines, and more particularly to whatis known in the art as a lining-beveler for bevelin g the edge andcutting the face of a plate for printing purposes.

A practical embodiment of my invention is represented in theaccompanying drawings, in which Figure l represents the top plan View ofthe machine. Fig. 2 is an end view of so much of the machine as isrequired to illustrate my invention. Fig. 3 is a view iu detail of thehandle for manipulating the gravercutter. Fig. 4 is a view in detailshowing in side elevation the removable bracket which carries theadjustable gage for indicating the line of cut. Fig. 5 is a transversesection of the same along the line 5 5 of Fig. 4. Fig.

6 isa View in detail showing in vertical section the micrometermechanism for adj usting the table; and Fig. 7 is a vertical transversesection through the table and carriage, showing the means for holdingthe table yieldingly on the carriage and for taking up lost motion inconnection with the micrometer adjustment mechanism. p.

The top of the pedestal whichv forms the bed-plate for supporting thes'e'veralparts of the machine is denoted by A.

The carriage B is mounted upon suitable ways b b to move back and forthon the bedplate A to carry the piate to be operated- .upon intoengagement with the beveling cutter or cutters and the lining-cutter orgraver. The plate to be operated upon is supported on .l a table C,carried by the carriage B, and while having a movement bodily along withthe carriage also has a limited movement transversely of the carriage,this limited transverse movement for adjusting the Vtable to a Qmicrometer-disk d3, which is graded with relation to the distancebetween two consecu- A shaft c is mounted in suitable bearings in thecarriage B and extends from 4the front of the' carriage to a pointpreferably beyond the center of the table C and is provided with aSpur-wheel or pinion c,which engages a rackbar c2, located on the underside of the table C, preferably at or near the middle portion of thetable. At its front end the shaft cis provided with a segment-gear D,fixed to rotate with the shaft, which gear D is arranged to engage aWorm CZ on a short vertical shaft d. The shaft d is mounted in a bracketb2, fixed to the carriage B, and is provided with a knurled thumb-wheeld2 for convenience in turning it. The wheel cl2 is provided with aconcave face in which is seated and loosely mounted on the shaft d adisk cl3, provided of movement of the shaft cl', and hence through thesector vD of the shaft c, which in turn through the spur-wheel c andrack-bar c2 determines the movement of the table O With graduations fordetermining the amount toward and away from the beveling and uated scaleon the periphery of the disk d3.

The arrangement of the disk d3 to be moved b v loosening the nut d4independent of the Wheel d2 and shaft'cl' is for the purpose of settingthe disk d3 in position, with its zeropoint'at the index-finger b3,without disturbingthe table after the latter has been moved to its limittoward the cut. of taking up all lost motion between the rackb`ar c2 andpinion c and between the sector D and worm d, I provide a pair ofsprings E, in the present instance spiral springs, having one endsecured to the under side of the table C and their opposite end to thecarriage y B. Thesesprings tend to hold the table at the limit of itsforward ladjustment toward the cutter or cutters, so that its .movementin the opposite direction, whatever there is,

will be entirely due to the result of the worm d and may be accuratelydeterminedby the tive teeth on the worm. To further provide for holdingthe table securely on the carriage against liability to tilt from itsbearings, I

A-stationary index- For the purpose IOG 2 crepe? employ springs e, whichsurround pins e', projecting downwardly through slots in the ears h4 onthe carriage B, the springs being inserted between the under side of theears b4 and a nut e2 on the lower end of the pin. The clampF for holdingthe plate in position on the table C and operated by the wheelf on theworm-shaftj", engaging a pinion-shaft f2, mounted in suitable bearingson the table, is quite similar in all respects to that heretofore in useand forms specifically no part of my present invention. Thevposition ofthe i head for carrying the beveling cutter or cutters is denoted by Gon the shaft g, mounted in suitable bearings on the bed A and providedwith a pulley g' for imparting rotary motion thereto from a source ofpower. (Not shown.) These parts, as well as the turret H, supported fromthe standard which supports the drive-shaft and carrying thesupport-arms h h for holding the adjustable bearings 7b2, in which thevertically-rocking tool-holder h3 is mounted, are quite similar in theirgeneral structure and arrangement to the corresponding parts shown,described, and claimed in Letters Patent No. 641,470, granted to me onthe 16th day of January, 1900, and, with the exception of the removablehandle for manipulating the graver-support h3, form specifically no partof my present invention.

For the purpose of pressing the tool into the surface of the plate tothe desired depth, I have provided in addition to the usual thumb-piecea removable handle I, suitable for receiving the grasp of the hand ofthe operator, and have provided the tool-holder 71.3 wit-h a socket t'for receiving the shank z" of the handle whenever it is desired tooperate the tool for making deeper cuts, the arrangement being such thatthe handle I may be inserted in position to aord the proper purchase toeasily force the tool into the surface and removed from its socket in amoments time at pleasure, thereby utilizing one handle for each of thetwo or more toolsupports, which may be swung into cutting positionwithoutpermanentlyincreasingtheir length to an awkward extent, whichmight interfere with the operation of otherparts of the machine.

To adjust the plate on the table C in position to receive one or morelining cuts, which shall have the desired relation to the insideborder-line of the engraving and also with respect to the beveled edgeof the plate, Iprovide an adjustable gage as follows: The gage properconsists of a thin plate K, having its operating edge serrated, as shownat 7c. The plate K is secured to a support 7c', bifurcated at its rearend to embrace the socket Z in the top of arocking arm L. The support 7cis held in rocking position in the top of the arm L by means ofpoint-bearings 7a2 k3, arranged to engage shallow tapered sockets in theopposite ends of the socket-piece l, hereinabove referred to, and thesaid gage-plate K is held normally in a position above the surface ofthe table by means of a spring Z, fixed to the back of the arm L, withits free end in position to engage a toe-piece Z2, depending from thesupport 7a'. The rocking arm L is preferably made in skeleton form, itslower end being secured by means of pointbeariugs m m (see Fig. 4:) tothe forward end of a bracket M, which extends from the bed A forwardlyand downwardly along the inner edge of the carriage B and table C. Thesaid bracket B is made removable from the bed A by means of suitablescrews m2. The said bracket is preferably made of skeleton formation topermit the pivot of the rocking arm or support L to be located centrallyin the bottom of its front portion and also to permit the passage of anextension lAl on the rocking arm below the pivotal support for theattachment of a spring l5 to hold the arm normally away from the edge ofthe plate against the micrometer-screws for adjusting it.

In the use of a machine of this character the beveling-cutters whenremoved for grinding and again adjusted for use assume aline of' cutslightly different from the line which they out before they were ground,and it becomes important to adjust the gage K to this new line of cut,which for convenience I call the Zero-line. To accomplish this, Iprovide an adjusting-screw N, which engages a screw-threaded perforationthrough the wall of an uprising portion 'm3 of the bracket M and extendsinto engagement with the back of the rocking support L. This screw N isintended to hold the arm L at all times in position, so that the freeedge of the gage will indicate the line of cut-t'. e., the zerolne-andas the zero-line, for reasons which I have above stated, changes at eachgrinding of the set of beveling-cutters the screw N moves the gage up toor back to a newr Zeroline, and is there locked in the present instanceby a suitable tail-nut n.

To adjust the gage K with respect to the zeroline for the purpose ofindicating the position on the margin of the plate where thegravercutter shall engage it, I provide a micrometer-screw O, whichworks within an interiorly-screw-threaded sleeve o and is operated bymeans of a hollow cap o', the edge o2 of which traverses the exteriorgraded portion of the sleeve o and determines the amount of distancewhich the screw O pushes the rocking arm L, and hence the gage K, overthe margin of the plate. To further provide for adjusting the gage whenset at zero to the position which the arm L occupies under the varyingZero adjustments of the screw N, I locate the sleeve 0, which holds themicrometer-screw, in a split socket in the top of the arm m3, where itmay be clamped by means of a clamp-screw m4. A jam-nut of on the IOO IIO

inner end of the screw O serves to look the latter in its adjustedposition.

The gage K and the micrometer table adjustment may either be utilizedsingly for moving the plate into different positions relatively to thecutters, but they have an important action conjointly in the followingmanner: Suppose, forexample, itbe required to provide a plurality ofgraver-cuts near the margin of the plate. The gage K is first adjustedto zero by running a trial-plate into engagement with thebeveling-cutters'and then bringing the edge of the plate K up to thiscut and operating the screw N to hold the gage in that position. Themicrometer-A screw O is thenset to zero and bodily moved forward' untilit just contacts with the arm L when the latter bears against the innerend of the zero-screw N. Suppose the graver-cut is to be an eighth of aninch in width, leav-` ing a printing margin of a sixteenth of an inchbetween it and a succeeding cut. The micrometer-screw O will be operatedto set the gage K forward an eighth and asixteenth. The trial-platebeing removed from the table and the plate to be operated upon havingbeen placed upon the table with the latter moved toward the cutters tothe limit of itsA movement and the micrometer-adjuster set with the gaged3, having its zero-mark at the index-finger b3 and the free edge of thegage K on the inner line at the border of the engraving, thegraver-cutter, carried by the arm h3, having been set forward tocorrespond with the advanced position of the edge of the gage K-vl. e.,under the present conditions an eighth and sixteenth-it follows that thegraver-cutter willcut from the margin of the engraving for an eighthofaninch and that the beveling-cutter, assuming it were to be brought intoaction would cut on a line a sixteenth of an inch still farther towardthe edge of the plate, thereby leaving a printing-line a sixteenth of aninch in width; but instead of operating the beveling-cutter at thismoment I leave the beveling-cutter out of action and form a cut with thegraver-cutter. Then utilizing the micrometer table-adjuster I advancethe table away from the cutter another eighth and one-sixteenth of aninch and again pass the plate into engagement with the graver-cutterand, if two marginal lines are required, set the beveling-cutter inaction, so that the beveling cut will be made within a sixteenth of aninch of the second graver cut, thus leaving two marginal printing-lineson the plate, with a graver cut intermediate of the margin of theengraving andthe first printing-line, a second graver cut between thetwo lines, and a beveling cut exterior to the outer line. The plate maythen be turned at right angles to its former posi# tion, and without anyfurther adjustment ofof the gage K. By means of the removable bracket,forming a support for the gage, as hereinabove set forth, the latter maybe removed from the machine when the table and its micrometer adjustingmechanism are alone sufficient to perform the work in hand.

What I claim isl. The combination with means for holding the plate to beoperated upon in position and a cutter for operating upon the plate,of agage for indicating the line of cut and a substantially upright rockingsupport for the gage, substantially as set forth.

2. The combination with means for holding the plate to be operated uponin position and a cutter for operating upon the plate, vof a gage forindicating the line of cut, the said gage .being mounted in rockingadjustment in a rocking support,substantially as set forth.
